Awesome, Thank you!

I don't actually have much for you to work with right now. This will be an ongoing project over the next month or so. I laughed a bit when I clicked your link... It's actually the snowmobile trails in my area that I am trying to map out. Our local club does an awesome job with maintaining the trails, but they have no online presence at all, and they never bother to submit their trail information to other sites like VAST or any mapmaking sites like GPS Trailmasters. So I decided I would try doing the mapping myself so I have something I can use while I am out riding.

I've downloaded GPSMapedit and I am poking around in it now. I can't figure out how to convert anything to an IMG, but I will keep at it and see if I can figure this out. Thanks for the information!

I've spent the past day or two playing with GPSMapedit, and I can get the trails to show up on the map just the way I want now. But one issue I am still having: I cannot figure out how to make it routable.
